' oomrnnserrne MECHANISM, 7

Application filed May 22, 1922. Serial N0. 562,923.

To all whom it may concern Be it known that I, RICHARD LESTER l/VIL- COX, a citizen ofthe United States, residing at Waterbury, in the county of New 'Haven and State of Connecticut, have in vented certain new and useful Improvements in Compensatinglvlechanisms, of which the following is a specification, reference being had therein to the accompanying drawings. This invention relates to compensating mechanism particularly as applied to heading or upsetting machines, although not limited thereto.

It is the object of this invention, among other things, to provide a simple andeificient device so associated with the means for operating a movable part, such as a punch slide, that'variations in the position of the movement thereof maybe made without requiring adjustment of its operating means. Among other aims and objects of the invention may be recited the provision of a device of the character mentioned with a view to compactness, in which the number of parts are few, the construction simple and both efficiency and operation high.

The details and arrangement of parts will be apparent from an inspection of the accompanying drawings in connection with the" description hereinafter contained and whereln a preferred embodiment of'the in-' vention is disclosed for the purpose-ofimparting an understanding of the same. 7 y In thedrawings;

Figure 1 is a side elevation of the form of my mechanism as applied to a heading or upsetting machine, the portioniof the latter immediately adjacent thereto being also shown; and

Figure 2 is a sideelevation, partly in section, ofthe connectingrod and of several of the associated parts."

.t is necessary from time to timein heading or upsettingmachines to vary the relative position ofthe slide upon the gate. This has required in the past an'adjustment of the stop mechanism connected'with the gate and slide and also an adjustment of the parts that actuate the rock shaft and impart movement to the slide. The stop devices "punches 16 therein.

connected with the slide and gate are so located as tobe conspicuous and within easy reach of the'operator, hence are always manipulated for adjustments; while the parts associated. with the rock shaftare usually so located as not to be so readily accessible and manipulation thereof is frequently overlooked. Then this occurs the relative movement of the punch slide is both uncertain and inaccurate and undue str'ainiis placed upon the parts which frequently break,

With my improved mechanism it is only necessary to obtain the adjustment of the punch slide by the stops and the parts that operate the rock shaft automatically adjust themselves.

In the drawings wherein like characters of reference'designate corresponding parts in the several figures,l0 is a portion ofthe frame of a heading or upsetting machine, 11 the gate that has a reciprocatory movement therein, 12 the rock shaft journaled in-the bearings 13 connected with the frame 10, and let the punch slide, to which is adjustably secured the punch block '15" having the Thisslide is movably mounted in the front end ofthe gate 11.

Connected with the rock shaft 12 are arms and 18, the former of which is Connected with the punch slide 1d throughthe stud 19 in a manner well-known .to the-art. The

source of power to operate" the punch slide is tv relation to the gate is limited by the nuts 44 threaded on'the stud 45 fixed in'the gate 11,. and passing through theslide lug'tfi.

-lts down position is limited by the stop screw4 7 which is threaded through the big -i6 and. contacts with the topof the gate.

This method of the adjustment of the stroke and position of the-punch slide is old and the one always utilized by the operator, sometimes, however, in the types ofheaders heretofore made, ;to the neglect of the rock shaft operating mechanism and necessary to fully accommodateithe punch slide in its adjusted limits. v

" All of the parts above described as well as the operation thereiif are now well known in the header art and require no further description herein.

The numeral 22 designates the connecting rod upon which is rotatably mounted a cam roll 23 that travels in the path 2 of the cam 21 and having a yoke end 25 between the walls of which is a slide block 26 that journaled upon the shaft 20.

The end of the connecting rod opposite to the yoke end 25 is slotted at 27 and the open end thereof covered by the cap 28 secured in' position by bolts 29 or similar means.

Movable between the walls of the slot 27 is the slide block 30 projecting laterally from two sides of which are the rods 31 and 32. the former extending through an opening 3?; and a transverse wall of the connecting rod 32 and the other through an opening 3 in the cap 28.

Surrounding the rod 31 is a coil spring and a similar spring 36 surrounds the rod 32, these being held in position and under variable tension by the nuts 37 and washer I have shown in the drawings these rods 31 and 32 as being made integral with the slide block 30 but obviously either one or both may be independent thereof and secured thereto in any desired manner.

Fixed to theouter end of the arm 18 by the nut 39 is the stud 4-0 which projects through the slide block 30 and is 'irovided with a washer 41 and nut 42 on its outer end. A collar 43 upon the stud e0 prevents endwise movement of the slide block 30 upon the stud in one direction.

Motion is imparted to the slide let. from the shaft 20 through the connecting rod 22 slide block 30, stud 40, arm 18, rock shaft 12 arm 1? and stud 19 my means of the engagement of the cam roll 23 with the cam groove 24.

As shown in the drawings the punch slide let is in its down position and the connecting rod 22 is in its extreme outer position relatively to the shaft 20 and springs and 36 are so adjusted that no tension is applied thereto. However a variation of the relative position of the slide 14 through the stop screw 7 or nuts 44- will also vary the outer extremc positions of the arm 18 and stud "l0.

the length of the stroke of the connecting rod 22 is not variable any change in the extreme positions of the stud 4.0 in either direction are accommodated by the compression of either one of the springs 35 or 36 depending upon the direction of such change.

,Minor changes and alterations may be made within my invention aside from those herein suggested and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of the appended claims.
